UNlTED STATFid T WILLIAM T. HUDSON, OF ATLANTA, GEORGIA, A$SIGNOR TO HUDSON STICK CANDY MACHINE 00., OF ATLANTA, GEORGIA.

CANDY-MAKING MACHINE.

To all whom it may concern:

lle it known that I, WILLIAM T. HUnsoN, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful improvements in Candy-Making Machines, of which the following is a specification.

My present invention pertains to machincry for producing what. is commonly known as stick candy, and is designed more tmrticularly as an improvement upon the machine constituting the subject matter of my Letters-Patent No. 910,198, granted January 19, 1909.

One of the objects of the present invention is the provision of spinning rolls and roughness-etl'acing or smoothing rolls, formed of carborundum or analogous material and partly clad in metal or other suitable material, whereby they are prevented from chipping and are enabled to withstand without deterioration the usage to which such rolls are ordinarily subjected.

Another obiect is the provision of means for exerting lding pressure against and holding the twister-bodies under tension and rigid or steady as the same move upward and rearward at the forward end of the ma chine where they receive the strip of candy material, this in order to assure such movement of the twister bodies without shaking thereof, and to enable certain parts carried by the twister to properly engage the strip and otherwise operate with certainty, as well as to enable the lateral projections of the twister bodies to properly enter the forward ends of the guideways of the frame.

Another object is the provision of imiroved means for putting the twisting heels in the twister bodies in positive enment with the strip of candy material t he proper timc-namely at the com- ;nencement of the upper traverses of the twister bodies, and for releasing the strip of candy material from said wheels at the end of said upper traverses of the twister bodies.

Another object is the provision of improved and highly efficient means for sevcring sticks from the strip of twisted candy material.

another ob ect is the provision of means for drawing thestrip of candy material reawvard between the smoothing or rougha i 1 v o ness-effacmg rolls (which rolls. because of Specification of Letters Patent.

their smoothness, are not adapted to take hold of and feed the strip), and for feeding the said strip to the severing means.

Another object is the provision of simple and highly efficient means for supplying air under pressure to the cooler comprised in the machine, with a view of inexpensively increasing the cooling capacity thereof.

Another object is the provision of a machine designed more particularly for twistin a strip of candy material and yet adapted, with slight adjustment and the employment of an interchangeable part, to form a strip of braid form and feed the same to the severing means and subsequently cool the braid sticks.

Another object is the provision of a safety belt intermediate the twisting means and the smoothing or roughness-efl'acing rolls-Lo, a belt calculated to carry a strip of candy material from the twisting means to the said rolls, and thereby obviate the necessity of the operator using his hand for such purpose and incurring the risk of having his hand mangled.

i rnotheirobject is the provision of a ma-- chine for the purpose stated, which, in general, is workmanlike, reliable in operation, and possessed of high capacity, and is adapted to be properly operated with the assistance of but few attendants.

My invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings which are hereby made a part hereof: Figure 1 is a plan view of the machine constituting the best practical embodiment of my invention that I have as yet devised.

Fig. 1st a plan view showing the upper portion of the tube broken away and the turning blade therein. Fig. 15 is an enlarged side elevation showing the notched disk carried by each of the twister bodies.

Referring by letter and numeral to the said drawings, and more particularly to Figs. 111 and 15 thereof: A is the main frame of the machine, which may be of the construction illustrated. or of any other construction compatible with the purpose of my invention without involving departure from the scope thereof. At its forward end the frame A provided with a shelf a and on said shelf are standards 6 in which are journaled lower and upper transverse shafts 0 and (Z, connected by intermeshed spur gears f, the lower shaft 0 being extended outward beyond one of the standards, and provided with a miter gear g, as shown.

Fixed on the shafts o and (Z and arranged one above the other in the longitudinal center of the machine are spinning rolls B and Ci. 6., rolls for reducing the strip of candy material to the desired shape and size in cross-section and feeding the same rearward.

The said rolls B and C are formed of coarse carborundumz'. 6., No. 100 carborundum, 0" equivalent material, and one or both are peripherally grooved; the shape and size in cross-section of the groove or grooves depending on the shape and size in cross-section it is desired to give the strip of candy material. Each roll is clad at opposite sides of its longitudinal center in shells D, of metal or other suitable material, (see Fig. and is thereby prevented from chipping and is strengthened and enabled to withstand the usage to which rolls of corresponding character are ordinarily subjected.

D D are fixed fenders which extend inward and rearward to a point in front of and adjacent the meeting portions of the spinning rolls B and. C, and have for their office to guide the candy material to said rolls.

E is a transverse shaft journaled in the forward portion of the main f ame A and bearing sprocket wheels F.

G a transverse shaft journaled in the rear portion of the main frame and bearing sprocket wheels H and having at one end a spur gear I, Fig. 1, and at its opposite end a gear J, Figs. 1 and 3, that is mitered at its side adjacent the frame, and l"; is a drive-shaft journaled in the main frame, at a point adjacent the shaft G, and having a spur pinion L intermeshed with the spur gear I and also having fast and loose pulleys if and N for the connection of a band (not shown) leading from a suit able source of power. Any suitable means may be employed for shifting the said band from the fast pulley to the loose pulley and vice versa, but inasmuch as said means does not form part of my invention, I have deemed it unnecessary to illustrate the same. ll would also have it here understood that I prefer to loosely mount the pinion L on the shaft K and to provide the said pinion with a clutch face that is opposed to a com plementary clutch member P on shaft K so that when the pinion is shifted by conventional means (not shown) out of engagement with the member P, the shaft G and the parts connected therewith will be stopped.

ll hen the pinion K is moved outward and clutched with the member P, the transverse shaft G will be driven from the drive-shaft K through the medium of the pinion L and the gear I and the shaft 0 of the lower spinning roll B will e driven from the shaft Gr through the medium of the miter gear J and a longitudinal inclined shaft Q; having, at one end, a miter gear 7b intermeshed with the gear J, and, at its opposite end, a miter gear 1'. intermeshed with the gear 9 of shaft 0.

After passing rearward between the spinning rolls B and C, the strip of candy material passes in the same direction through its) a fixed tube that is slightly tapered rearward. as illustrated. The said tube R is removaliily held in a clamp 7' on an arm K: which extends downward and forward from a cross-bar Z. supported in standards at rising from the sioes of the main frame A. From the rear end of the said tube ll. the strip of candy mz'tterial passes to the means for engaging and carrying the strip longitudinally toward the rear end of the machine and for twisting the strip during the said movement thereof. The said means comprises longitudinal parallel sprocket belts arranged on the sprocket wheels F and and driven by the latter; four (more or less), equidistant twister bodies T, connected to the belts S and having lateral projections a movable reaiavardly in tixed longitudinal guideways 7) which have flared mouths at their forward ends, Fig. 2, designed to facilitate the entrance therein of the said lateral projections a, strip-engaging and twisting wheels U, one of which is carried by each body T; latches V. one of which is carried by each twister body; a fixed longitudinal rack bar V a fixed longitudinal bar ll" having the underside of its forward end s beveled and designed to cooperate with the latches V in the manner hereinafter set forth in detail; fixed forward cam bars .7 and fixed rear cam bars Y.

Each of the tn ster bodies T is in the form of a generally circular easing having a radial projetion t Figs. 1" and i, and also havin a swell w; the projection 2/ receiving one or the twisting wheels U. and the major portion of the casing and the swell to thereof receiving the gearin for transmitting motion to said wheel U. The wheel U is provided with dished ends to facilitate its nioreinent into and out of engagement with the candy strip. and is also provided with a longitudinal lierit peri )heral ,e'ear teeth "to. and a lltl] e ,rse slot the latter boil' for the reception of pi oted bell'cranlts and pivoted bars 1 hair barbs a" which normall extend into the herf '2). The bars u against the 1 an o .i are arranged la. ween inner arms of the bell-eran s, and are connected to a coiled spring 2 which is interposed between them with a view of yieldingly holding both bars and bell-cranks in and returnin the same to their normal posilion. best hown in Fig. l". The outer arms of the l ltilliibl extend beyond the perimeter of the wheel U and are designed incidental to the rotation of the said wheel in the body T. to more in transverse slots 3 in the projection t said body. Int-en meshed with the teeth 20 the wheel U is a large gear wheel l. mounted in the ing body T and fixed with respect to a miter gear 5. and intermeshed with the said miter ear 5 is a miter gear 6 on a transverse shaft which is jonrnaled in the side walls of the swell a, Fig. 1, and carries at one end and exteriorly of the body a spur gear 8, and at its opposite end and exteriorly of the body a disk 9, peripherally notched at 10.

The spur gear 8 is designed to mesh. with the rack bar V and derive rotary motion therefrom during the upper traverse of the twister body T, with the resultthat during said traverse the twisting wheel U will be rotated and will twist the strip of candy disposed in the kerf 4.) thereof. 1 would also have it here understood that the wheels U of the alternate twister bodies T are synchronously rotated in opposite directions in order to effect the twisting of the candy strip; this being accomplished by arranging the miter gears 6 bodies T in front and rear of the twister body shown in Fig. l in the position shown by the dotted lines at the right-hand side of the miter gear 5 in Fig. 1 and the miter gear 6 of each of the remaining twister bodies in the position shown by full lines in Fig. 1*. From this is follows that while the spur gears 8 of any two twisting bodies T are in mesh with the rack bar V during the operation of the machine, the wheels U of the said twister bodies will be rotated in opposite directions for the purpose stated.

The dish 9 of each twister body T is pro vided with two diametrically opposite notches 10 (Fig. because of the diameter of the spur gear 8 compared with the length of the rack-bar V and the office of the latch V belonging to each twister body is to seat in one of the said notches 10 when the gear 8 of said body passes out of engagement with the rack-bar V at. the completion of the upper and rearward traverse of the body, this with a view of locking the twisting wheel U of the mentioned body against rotation so that when it reaches the point at which the upper, rearward traverse starts, its herf v will be in correct position to move rearward past the tube R and to receive and move rearwardly with the continuous strip of candy material. The latch V is fulcrumed an intermediate point of its length, and one of its arms is arranged to seat in one of the notches 10 of the dish 9 for the purpose stated, and its other arm is backed by a spring 11 and is adapt-och as the spur gear 8 moves into engagement with the rack V to be engaged and depressed by the bar W, this to release and permit of rotation of the gear 8 and the gearing between the same and the twisting wheel U together with said twisting wheel U. The latch V is held by the bar \V out of engagement with the disk 9 until the latch passes, at the end of the upper and rearward traverse of its twister body T, out of engagement with the bar W, and the gear 8 has passed of the twister out of engagement with the rack bar V whereupon the spring 11 will press the latch into one of the notches 10 of its complementary dish 9, for the purpose described. As each twister body T passes upward at the forward end of the machine prior to beginning its upper and rearward traverse, the outer arms of the bellc'anks 3 of the twisting wheel U carried by said body, move m ward and rearward under the cam bars X, the upper and rear portions of which serve to depress the outer arms of the bell-cranks 3 and thereby bring about outward movement of the barbs 2 so as to enable the kert o to receive in its innermost portion the strip of candy material. Then when the outer arms of the bell-cranks 1 pass rearward from under the cam bars X, the spring 2 forces the barbs .2 into engagement with the strip of candy material with the result that the strip, turning with the wheel U, will be twist-ed or turned about its axis.

At the proper timena1nely immediately precedent to the downward movement of each twister body T at the end 01 the rearward traverse thereof, the outer arms of its bell-cranks y pass under the cam bars Y and are depressed thereby, and hence the barbs .2 are drawn outward out of the strip of candy material, and the wheel U, which is then locked againstrotation is enabled to pass down and out of engagement with said strip, leaving the latter tree to move rearward as presently described.

With a view of supporting the strip of candy material between the twister bodies T during the upper traverse ot the latter, I employ in the strip-carrying and twisting mechanism a plurality of cradles Z. These cradles are arranged in longitudinal series intermediate the twist-er bodies T and each is connected with the sprocket belts S by a carrier Z as clearly shown in Fig. l.

it is important and in tact essential to the reliable operation of the machine that the twister bodies T move upward to the point where they commence their rearward traverse .in a steady manner and without lateral or other play. To meet this requirement 1 provide the coiled spring A best shown in Figs. 2 and a. The said spring is loosely mounted on the shaft E and is interposed and held under tension between the sprocket gear F or other suitable abut ments that may be provided. It will also be noted by reference to Fig. 4 that the spring A is tapered or gradually diminished in diameter from its middle to its ends, this to increase its efficiency.

As will be readily understood by comparison of Figs. 2 and l, each twister body '1, as it approaches the end of its lower traverse, moves into engagement with and crowds the spring A and consequently the said spring exerts yielding pressure against and holds the twister body steady and against play laterally from its path. This continues until the twister body T commenccs its upper and rearward traverse, with the result that tree reception of the strip of candy material in the kert o is assured, and the late "al projections n of the twister body are enabled to accurately enter the forward ends of the guideways 2), while the spur gear 8, the latch V and the outer arms of the bell-cranks 11 are adapted to exactly and otherwise properly engage the raciobar V the longitudinal bar W and the fixed cam bars X, respectively.

From the mechanism described for carrying the strip of candy material and twisting the said strip about its axis during the carrying thereof, the strip passes to a longitudinal belt A the upper stretch of which is arranged in a longitudinal trough A, and from said belt and trough the strip passes to the smoothing or roughness-ettacing and shaping rolls 13 G By guiding the strip of candy material to the rolls B and G the belt A} and trough A obviate the necessity of an attendant using his hand and incurring the liability of mangling the same.

The rolls B and C are formed of com paratively line carlwrundum, approximately No. 220, and are clad in metallic or other suitable shells in the same manner and for the same purpose as the rolls B and C. The rolls B and C are also circumterentially grooved, but their grooves are smaller than those of the rolls B and C as is necessary in order to enable them to effectually smooth or tree the strip 01 roughness. The grooves of rolls B and C being smaller than those of the rolls B and C it necessary to drive the rolls 13 and U about sixteen more revolutions per minute than the rolls B and C in order to enable the said rolls B and C to take up the surplus candy, and inasmuch as the rolls B and C reduce the size oi the strip of candy material. and shape the same it is proper to denominate them smoothing and shaping rolls. 1 would also have it here understood that I: prefer to employ in advance of the rolls B and C fenders or guides D similar to the tenders D in advance of the initial rolls B and C. The shafts of the rolls 13 and C are connected together by intermeshed spur gears 13. and the shaft of the lower roll is extended as indicated by in Fig. 1 and provided with a miter gear 15.

Intermediate the miter gear J and the miter gear 15 on the shaft 14: is the driving connection best shown in Figs. 1 and 3, which driving connection comprises a horizontal shaft 16 having miter gears 17 and 18, and a vertical shaft 19 having miter gears 20 and 21 intermeshed with the gears 15 and 18, respectively.

After passing between the rolls and C and being smoothed or freed of roughness, the strip of candy material passes to a longitudinal belt s3, the upper stretch of which is arranged in a fixed longitudinal trough et that is open atits opposite ends. The said belt passes over a rear idler wheel 25 and a forward wheel 26 which latter is fixed on a shaft 27 having a spur gear 28 that is connected through a pinion 29 (Fig. 2) with the lower spur gear 13. Thus it will be manifest that the belt 23 will be driven from the lower of the smoothing or roughnessetlacing rolls.

Fixed on a transverse shaft 30 mounted in suitable bearings above the shaft 27 is a wheel 31 which is provided with a spur gear 32, and is driven from the upper spur gear 13 through the medium of the pinion Fig. 2.

Loosely mounted on the shaft 30 is a vertically swinging frame 3 lwhich extends rearwardly from said shaft, and mounted in said frame, near the free end thereof, a wheel 35. A belt 36 is mounted on the wheels 31 and 35. and the lower stretch of said belt is movable in the trough 2t above the upper stretch of the belt 23, as best shown in Fig. 2. It will also be seen by comparison of Figs. 2 and 3 that the frame 3i carries hangers 37 in which are slots 38, and that in said slots are arranged the trunnions of a heavy wheel 39 which by hearing on the lower stretch of the belt 36 causes a' portion of said stretch to move approximately parallel to the upper stretch of the belt 53. The wheel 39 combined with the gravitation of the frame 34: serves to hold the lower stretch of the belt 36 under yielding pressure adjacent the upper stretch of the belt 23, and consequently the two belts will serve to engage and positively feed the strip of candy rearward. This will be appreciated as necessary step when it is remembered that the rolls B and C are necessarily smooth and because of such smoothness are notadapted to take hold of and feed the strip of candy material rearward.

lVith a view of enabling an attendant to regulate the extent to which the free end of the frame 3-1 can move downward, 1 provide on the main frame vertically adjustable supports 40, designed to coiiperate with lateral projections on the main frame 34:.

By adjustment of the said supports 4-0 the j frame 3% can be maintained at the proper 1 height to position the belt 36 relative to the belt 23 and lessen the tension of the belt 36 on the strip of candy material as condi tions require. It is obvious that the supports 40 may be of the construction illustrated or of any other construction consonant with their function.

On the belt 23 the continuous strip of candy material is carried to the severing mechanismz'. 6., the mechanism for separating sticks or sections of common length from the strip. This mechanism, as best shown in Figs. 1, 2, 3, and 5 to 8, comprises a sub-frame fixed transversely on the rear portion of the main frame A; a wheel 51 having peripheral spur-gear teeth 52 and also having diametrically opposite blades 53, and further having an upwardly extending tubular projection 54: (see Fig. 6); a miter gear 55 fixed on the upper side of the wheel. 51; a wheel 56 having peripheral gear teeth 57 intermeshed with the beforementioned teeth 52, and also having a chamber 58 and an upwardly extending tubular.

projection 59; plungers 60 and 61 carried by the wheel 56 in the chamber 58 thereof and having blades 62 and 63, respectively, and also having vertical projections 64 and 65, one of the said plungers, Viz: the plunger 60, being adapted to telescope in the inner tubular portion of the other plunger 61 after the manner clearly shown in Fig. 6; a ring 66, Figs. 6 and 8, arranged above the wheel 56 and having a depending flange 67 on the inner side of which is a cam 68, and also having an upwardly extending tubular projection 69 which surrounds and is set-screwed or otherwise fixed to a depending tubular projection 70 of the sub-frame 50; a vertical bolt 71 which extends upward through the tubular projection 54: of the wheel 51 and has a head '72 at its lower end and also has its upper end connected to a screw 73 between the head of which and the top of the sub-frame 50 a washer 74 is interposed; and a vertical bolt 75 extending upward through the tubular projection 59 of the wheel 56 and having a head 76 at its lower end, and also having its upper end connected to a screw 77 between the head of which and the upper side of the sub-frame a washer 78 is interposed.

By virtue of the construction described, it will be manifest that when the wheel 51 is rotated, rotary motion will be imparted to the wheel 56 through the medium of the teeth 52 and 57. It will also be manifest that incidental to the rotation of the wheel 56 each of the plungers 60 and 61 will, by the cam 68, be retracted against the action of the spring 80 which surrounds the plungers and is interposed between and bears against the vertical projections 64 and thereof; the retraction of each plunger being due to the travel of its vertical. projection against the cam 68 toward the wide or thick end thereof. Then when the vertical projection of the plunger clears the cam 68, the retracted spring will suddenly expand and by so doing will impel the plunger outward and carry the blade thereof against the blade of the wheel 51, which is at that time opposite the blade of the mentioned plunger. It will be readily understood from this that a candy stick will. be eliicicntly severed from the continuous strip of candy material every time one of the blades of the wheel 56 meets or is opposed to one of the blades of the wheel 51; the said wheels 56 and 51 being rotated in the direction indicated by arrow in Fig. 1. i ittention is also directed to the fact that the vertical projections 64 and 65 of the plungers in the wheel 56 are guided in slots 81 in the said wheel so as to enable the vertical projections to move rectilinearly with the plungers and also enable said projections to extend up into the fixed ring (it) so as to be acted on by the before-mentioned cam (58 during the rotation of the wheel 56.

The wheel 51 of the severing mechanism discribcd is driven from the vertical shaft 19, Fi 3 and Fig. 1, through the medium of the miter gear 82 on said shaft, a horizontal shaft 83 having a miter gear 8a; intermeshed with the gear 82, and also having a miter gear 85 at its rear end, a transverse shaft 86 journaled in the main frame and having a miter gear 8? intern'ieshed with the gear 85, and also having a spur gear 88, a transverse shaft 89 journaled in the main frame and carrying the rear wheel of the belt 23, and having at one end spur gears 90 and 91 the former of which is intermeshed with the gear 88 a stub shaft 92 carried by the sub-frame a0 and bearing a spur gear 93 which is intcrn'ieshed with the spur gear 91, and a short shaft 9-1: journaled in the snb-frame and having at its outer end a spur gear 95 intern'ieshed with the gear 93, and also having at its inner end a miter gear 96 which is intermeshed with the miter gear 55 fixed on the wheel 51.

Fixedly mounted on a transverse shaft 97 arranged in rear of and slightly below the severing mechanism, is a ln'acliet 98 which carries two longitudinal and spaced walls The said shaft 8.)? is provided with a depending arm 100, and in said arm is mounted a screw 101 which is designed to be adjusted against a fined transverse rod 102 with a view of enabling an attendant to level the bracket 98 and the upper stretch of the fast belt presently described, or else incline said bracket and belt stretch slightly from the horizontal as occasion demaniils. As will be seen by reference to Fig. 1. one

of the walls 9%) is much longer than the other, in order to enable it to overhang the same at a higher rate of speed than the belt- 223. This necessity will be appreciated when t is borne in mind that were the belt lOl' caused to move at the same speed the belt 223, the strip of :andy material would be liable to be connected again to a severed stic it being understood of course that the can n'iatcrial handled is in a heated state. I would also have it understood that it is desirable to drive the belt 10? a comparatively high rate of speed in order to enable the said belt to chute the candy sticks from its upper stretch into the compartments of the cooler conveyor. The belt 10? is driven from the shaft 89, Figs. 2 and 5, through the medium of a spur gear 110 on said shaft 89, a spur gear 111 on the shaft 105 of the belt, and a spur gear 112 intermeshed with the spur gear 110 and fixed with respect to a spur 113, which, in turn, is interineshcd with the spur gear 111. Because of said gearing the belt 107 will obviously be driven faster than the belt 23.

125 is the cooler. The said cooler has a conveyor 1% to which the candy sticlvs are v plied by the belt 107, and is otherwise similar to the cooler constituting the subject matter of the contemporary application of Paul 11-. Camp and Thomas J. Eubanlcii, tiled Llovember 1, 1909, Serial Number 25,756. I would. have it distinctly understood, however, that while I nefer to cmploy the Camp and Eubanks cooler referred to, 1 do not desire to be understood. conf to the same, inasmuch as a fining niysel cooler of any other description consonant with the purposes of my present i vcntion may be employed without involving depar from the scope of the same as de lined in m y appended claims.

The driveshaft 130 of the cooler referred to is provided with a band pulley 131, and is driven from the drive-shaft K through the medium of a pinion on said driveshaft K, a stub shaft supported by the main frame A and provided with a spur gear 131 intermeshed with the pinion 132, and also provided with a pulley 135, and a band 131} arranged on the pulleys 135 and 131 and adapted to transmit motion frm the former to the latter.

lYith a view of supolying air under pressure to the interior of the cooler and utilizing such air under pressure or ourrents therefrom to expedite the dissipation of heat from the candy sticks in the cooler, I provide the closure plates M0 and 141, f) and 10, which are connected to the main frame of the cooler, and the air supply mechanism shown in Figs. 2, 9, 10 and 11. The said air supply mechanism coinprises a fan blower l-itl designed to be driven from the shaft 130 through the medium of the gears 14:3 and led, a trunk pipe 145 which extends upward from the blower casing and then horizontally through the closure plates H1 and l-l-O, and is closed at its end remote from the blower casing, and four (more or less) pairs of distributing pipes which are disposed in the cooler as clearly shown in Figs. 9 and 10. The distributing pipes are numbered 14. .7, and the pipes of each pair are arranged at opposite sides of and are joined to and communi "ate with tae horizontal portion of the trunk pipe after the manner shown in Fig. 11, so as to permit the free passage of air from the trunk pipe to the branch pipes. It will also be seen by reference to Fig. 11 that the ends of the distributingpipes are closed, and that each distributing pipe is provided in its outer portion with a plurality of eduction apertures 14S designed to direct the currents of air to trays 1&9 disposed in vertical series at opposite sides of the battery of distributing pipes.

With a view of equalizing the distribu tion of the air under pressure to all portions of the candy sticks on the trays 149, I graduate the eduction apertures of the pipes let? in the manner illustrated in Fig. 9-that is to say, I make the eduction apertures of the pair of pipes nearest the fan blower comparatively large and gradually diminish the size of the apertures as the pipes in which the apertures are formed re cede from the fan blower. By virtue of this provision it will be manifest that the candy sticks in the portion of the cooler adjacent the pair of pipes farthest from the fan blower will be supplied with as much air as the candy sticks in the portion of the cooler adjacent any other pair of the air distributing pipes In Figs. 12, 13 and 14 is illustrated a tube R which is designed to be used in lieu of the tube R, Figs. 1, 2 and 3, when candy sticks of the braid type are to be produced in lieu of twisted sticks. I would also have it here understood that when braid sticks are to be produced rolls will be used in lieu of the rolls B and C, provided with circumferential grooves of such shape in cross-section as will give the candy strip the braid shape or configuration in cross-section. I would further have it understood that when braid sticks are to be produced the rack bar V entirely removed so that the twisting wheels U will not be rotated in the twister bodies T, and the upper of the smoothing rolls 2'. 6., the roll C will be maintained in a raised position so as to serve in combination with the lower roll as a guide for the strip of braid form in cross-section. The spinning rolls used for the braid type will feed the braid form of strip rearward in such position that the greatest width of the said strip will be horizontal, and inasmuch as it will be necessary to have the grea; width of the braid strip vertical in Ol'httl to enable the same to enter the kerfs of the twisting wheels U and be engaged by the barbs I provide the tube with an interior blade or deflector R the o'tlice of which is to turn the strip so as to change the greatest width of the same from horizontal to vertical. After leaving the tube R the braid strip is carried in the kerfs of the wheels U and engaged by the barbs 2 in the same ananner as before described with reference to the strip to be twisted, and after passing from the wheels U at the completion of the upper traverse thereof, the braid strip is carried past the severing means by which it is divided into sticks, and the sticks are then conducted to and through the cooler in exactly the same manner as before described with reference to the strip that is twisted about its axis. I have deemed it unnecessary to illustrate the initial spinning rolls for use when sticks of braid form are produced, inasmuch as such rolls differ from the rolls B and C only in the configuration of their circumferential grooves.
